Take a minute to look at the room and furnishings around you. Virtually everything you will see is at least partially comprised of organic-based building blocks. From the plastics that surround electronic components to individual carpet fibers, no other type of material is as heavily utilized in our society as organic-based polymers. As first defined by Staudinger in 1920, a polymer is any material that is comprised of an extended structure of small chemical repeat units, known as monomers. For simplicity, the monomeric unit is almost always clearly identified within the polymer name (i.e., “poly(monomeric unit),” Figure 5.1). A polymer is generally comprised of more than 100 repeat units; structures with lower numbers of chemical repeat units are known as oligomers. Strictly speaking, all solid-state materials with an infinite structural array are classified as polymers – even inorganic structures such as metals, ceramics, and glasses. However, since we have described inorganic-based materials in previous chapters, we will focus our present discussion on polymeric materials that feature a carbon-containing backbone.

- 1.It should be noted that melting points refer to the temperature required to separate molecules from one another. By contrast, the glass-transition temperature refers to the temperature required to perturb the bonds of the polymer backbone.Google Scholar
- 2.Gel-permeation chromatography (GPC) is a subdivision of size-exclusion chromatography (SEC), in which macromolecular species are separated from one another based on their size. As its name implies, GPC employs a gel (usually cross-linked polystyrene) as the stationary phase, with detection through either light-scattering or refractive index.Google Scholar
- 4.In general, high molecular weight polymers are typically formed from catalysts derived from early transition metals (Groups 4-6). For late transition metals, the β-hydride elimination mechanism is more preferred, leading to greater numbers of oligomers and dimers.Google Scholar

- 9.It should be noted that Robert Denkwalter and coworkers from Allied Corporation were granted the first patent for dendrimers (US Patent 4,410,688 - filed 11 December 1981 and published 18 October 1982: http://www.hairlosshelp.com/html/researchframepatentus.htm), which represents the first dendrimer-related publication. However, the term “dendrimer” can be traced back to A. J. Vogel. The generally accepted definition of dendrimers is highly branched and monodisperse polymers (particularly for convergent growth), with a degree of branching of 1.0.
